If by workspace you mean the area where your image appears (red line) Just drag the panels in. If you mean where your layers are (blue line,) just drags them smaller. once you have them how you like them Save them as your workspace

Sounds to me, you mean your entire program takes up a large space on your monitor as your monitor is not large enough. You might have an older system. Resolution and image size can change between 32 bit and 64 bit systems. You can buy a larger monitor that has a smaller resolution to make it all fit, or you can buy a whole new system. In a 32 bit system, go to Windows control panel, or in a 64 bit system, go to settings to the display settings, and work with its resolution, and there are selections for the resolution provided by video card to Windows. This can change your image size for your screen. Bear in mind that most everything will be smaller but the entire program will be seen on the monitor. If you want larger font to be capable of reading the program, you might want it to stay the same. If you need help with resolution size numbers, ask a tech to see your screen as we cannot. The monitor itself has adjustments to change aspect ratio but that is not about the image dimensions, although one of them might adjust it into a morph so that he sides are squeezed into the screen. Select responsibly but don't mess it up. we cannot see it to fix it. If you are unsure of this, show it to a tech who can see the monitor. Steve Lehman, mcse responding;
